Abstract

The paper presents the development of the experimental stand for investigation of heating and drying phenomena in the porous building materials with one surface of the sample exposed to the flowing air. Moreover, the paper includes results of preliminary measurements which verify stability and the range of operating conditions of the stand. In order to control parameters of air used for heating and drying of considered materials the closed-loop concept of the stand was proposed and equipped with several elements, i.e., the cooler (vapour condenser), fan with variable rotational speed, humidifier and heater – see Fig. 1. Furthermore, two parallel measurement ducts which allow to obtain two air streams with identical parameters were proposed. This enables two measurements at one time as well as faster verification of the repeatability of the proposed investigation method. The specimen was placed in the duct with only one surface in direct contact with the flowing air. The position of the specimen in the duct might be changed, i.e., from bottom to either latera or top in order to investigate influence of the gravitational acceleration on the drying process.
